DETAILED DESCRIPTION OF THE EMBODIMENTS

Examples will be described in detail herein, with the illustrations thereof represented in the drawings. When the following descriptions involve the drawings, like numerals in different drawings refer to like or similar elements unless otherwise indicated. The examples described in the following examples do not represent all examples consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

The terms used in the present disclosure are for the purpose of describing particular examples only, and are not intended to limit the present disclosure. Terms determined by “a”, “the” and “said” in their singular forms in the present disclosure and the appended claims are also intended to include plurality, unless clearly indicated otherwise in the context.

In order to enable those skilled in the art to better understand the technical solutions according to the examples of the present disclosure, the technical solutions in the examples of the present disclosure will be described in further detail below in conjunction with the accompanying drawings.

Referring to FIG. 1, which is a flowchart of a method for processing data according to an example of the present disclosure, as shown in FIG. 1, the method for processing data can include the following steps.

It should be noted that the method for processing data shown in FIG. 1 can be applied to an electronic device that supports browser installation and data storage, such as a PC (PC is taken as an example below).

At Step S100, a data connection between a local service and a Web client is established.

In the examples of the present disclosure, a Web page displayed by the Web client (that is, a web page accessed through a browser) can be used to represent the Web client.

In the examples of the present disclosure, considering that some browsers cannot store data locally on the PC, but can only store data in the memory of the PC, when the amount of data is large, it will occupy a large amount of the memory of the PC. Therefore, in order to enable the browser to store data in the local storage space of the PC (such as a disk), and a service (hereinafter referred to as local service) can be started in the PC for storing the data received by the browser (such as the data received from the Web server) to the local storage space of the PC. The local service can be a background application in a form of a process that runs in the background which is configured to store the data received by the browser in the local storage space of the PC.

Here, the local service and the Web client run independently of each other, and the local service does not rely on the Web client (or browser) to run.

Correspondingly, in this example of the present disclosure, the local service can establish a data connection with the Web client.

Here, the data connection can include, but is not limited to, a Websocket connection or an HTTP (Hypertext Transfer Protocol, hypertext transfer protocol) connection, etc.

For example, w % ben the Web client is started and it is determined that it needs to obtain data from the server, the Web client can detect whether the local service has been started, and when the local service has been started, the Web client can initiate a connection establishment request to the local service. When the local service receives the connection establishment request, the local service can establish a data connection with the Web client.

Here, the specific process of data connection between the local service and the Web client is not described here.

At Step S110, data that the Web client transmits to the local service through the data connection is received.

In this example of the present disclosure, after the Web client establishes a data connection with the local service, the Web client can send the received data (such as data sent by the Web server) to the local service through the data connection.

Correspondingly, the local service can receive the data transmitted by the Web client through the data connection.

At Step S120: the received data is stored in a designated local storage space.

In this example of the present disclosure, the local service can store the data received through the data connection (with the Web client) in the designated local storage space.

Here, the designated local storage space can be a designated file directory in the local file system of the PC.

For example, when a local service establishes a data connection with a Web client, a file directory for storing the data of the Web client can be created in the local file system of the PC.

When the local service receives the data sent by the web client through the data connection, the local service can store the received data in the file directory.

It can be seen that in the method flow shown in FIG. 1, by starting a local service in the PC for storing the data of the Web client to the PC, in the case where the browser does not support storing the data to the PC, the data of the Web client can be stored locally on the PC, which can prevent the data of the browser from occupying the memory of the PC and improve the reliability and stability of the system.

Further, in the examples of the present disclosure, considering that a plurality of web clients can be running on the same PC (for example, a plurality of web pages opened on the same PC in the same browser, or a plurality of web pages opened in different browsers), In order to ensure the accuracy of data reading and writing for the Web clients, it is necessary to store data from different Web clients in a distinguishable manner.

Correspondingly, in one of the examples of the present disclosure, after the data connection between the local service and the Web client is established, the method can further include:

-   -   generating a target identifier, the target identifier is used to         uniquely identify the data connection;     -   storing data in the designated local storage space can include:     -   storing the data in the designated local storage space         corresponding to the target identifier.

In this example, after the local service establishes a data connection with the Web client, a data connection identifier (referred to as a target identifier herein) for uniquely identifying the data connection can be generated.

Correspondingly, the local service can allocate local storage space (that is, the above-mentioned designated local storage space) to the Web client associated with the target identifier; when the local service receives the data sent by the Web client through the data connection, the local service can store the received data in the designated local storage space corresponding to the target identifier.

Further, in the examples of the present disclosure, after the Web client receives certain specific data, the Web client usually needs to perform certain processing before storing the data, for example, transcoding the video data, etc. In order to avoid the problem of insufficient data processing capability of the Web client, the local service can process and store the data for the Web client.

Correspondingly, in one of the examples of the present disclosure, before storing the data in the designated local storage space, the method can further include:

processing the data according to a preset policy;

storing data in the designated local storage space includes:

storing the processed data in the designated local storage space.

In this example, when the local service receives the data transmitted by the Web client through the data connection, the local service can process the data according to a preset policy.

For example, for video data, the received video data can be converted into a specified format; or, for picture data, a picture of a size exceeding a preset threshold can be divided into multiple pictures of a specified size, etc.

In this example, after the local service processes the received data from the Web client according to a preset policy, the processed data can be stored in the designated local storage space.

It should be noted that in this example of the present disclosure, after establishing a data connection to the local service, the Web client can also send a data processing instruction to the local service, and the data processing instruction can include a data processing policy.

Correspondingly, after establishing a data connection with the Web client, the local service can also receive a data processing instruction sent by the Web client through the data connection, and before storing the data sent by the Web client through the data connection to the designated local storage space, the local service can process the data according to the data processing policy included in the data processing instruction, and then store the processed data in the designated local storage space.

Further, in this example of the present disclosure, the local service can use different storage methods for storing the data of the Web client according to actual needs, which can include temporary storage or long-term storage.

Here, in the temporary storage mode, the local service can be equivalent to a virtual file system, storing the data sent by the Web client through the data connection, and returning the stored data to the Web client when the data writing is completed, and delete the data stored in the designated local storage space; wherein the designated local storage space used to temporarily store the data sent by the Web client through the data connection can be referred to as a first designated local storage space.

In the long-term storage mode, the local service can store the data sent by the web client through the data connection in the designated local storage space for a long term, and return the storage path of the data to the web client for subsequent data access. Here, the designated local storage space used for long-term storage of data sent by the Web client through the data connection can be referred to as a second designated local storage space.

Correspondingly, in one of the examples of the present disclosure, after storing the data in the designated local storage space, the method further includes:

-   -   when the data storage is completed, sending the data stored in         the first designated local storage space to the Web client, and         deleting the data stored in the first designated local storage         space.

In this example, when the local service completes the data storage of the Web client, the local service can send the data stored in the first designated local storage space to the Web client, and delete the data stored in the first designated local storage space.

Here, when the Web client transmits data to the local service through the data connection, the Web client can send a data stop writing instruction to the local service when the data transmission is completed to notify the local service that the data transmission has been completed, and the local service can determine that the data storage is completed when the data of the Web client received through the data connection (that is, the data received before the data stop writing instruction is received) are stored in the first designated local storage space.

In this example, when the Web client receives the data returned by the local service, the Web client can prompt the user to download the data and store the data in the designated storage space (including local storage space or peripheral devices, such as a U disk, a mobile hard disk or the like), specific implementation will not be given to avoid limitation.

In another example of the present disclosure, after storing the data in the designated local storage space, the method further includes:

-   -   when the data storage is completed, sending the storage path         corresponding to the second designated local storage space to         the Web client.     -   In this example, when the local service completes the data         storage for the Web client, the local service can send the         storage path corresponding to the second designated local         storage space to the Web client.

In an example, in a subsequent data access process, the Web client can send an access instruction for the storage path to the local service, and the local service responds to the access instruction to access the storage path and perform data access under the storage path (that is, the data access of the second designated local storage space).

In another example, in the subsequent data access process, the user can also directly access the data stored in the storage path on the PC according to the storage path.

It should be noted that, in this example of the present disclosure, the data stored by the local service in the first designated local storage space or/and the second designated local storage space can be unprocessed data or data processed in accordance with the method described in the above example. Specific implementation will not be given to avoid limitation.

In addition, in order to increase the controllability of data storage, after the Web client establishes a data connection with the local service, the Web client can also send a data processing instruction including a data storage policy to the local service.

Correspondingly, after the local service receives the data sent by the Web client through the data connection, the local service can also store the data (which can be processed data or unprocessed data) according to the data storage policy included in the received data processing instruction, such as storing in the first designated local storage space (that is, temporary storage) or/and storing in the second designated local storage space (that is, long-term storage).

In order to enable those skilled in the art to better understand the technical solutions provided by the examples of the present disclosure, the technical solutions provided by the examples of the present disclosure will be described below with reference to specific examples.

Referring to FIG. 2, which is a schematic diagram of an application scenario according to an example of the present disclosure. As shown in FIG. 2, in the present disclosure scenario, a PC is installed with a local service 202 (taking the Websocket service as an example) for storing data received by the Web client 201 in the local storage space 203 of the PC, the local service is a background application in a form of a process that runs in the background.

Referring to FIG. 3, in this example, when the Web client is started and determines that the Web client needs to obtain data from the server, the Web client can detect whether the local service has been started, and when the local service has been started, the Web client can initiate a connection establishment request to the local service.

When the local service receives the connection establishment request, the local service can establish a data connection with the Web client, generate a UUID (Universally Unique Identifier) used to uniquely identify the Websocket connection, and allocate designated local storage space corresponding to the UUID to the Web client.

In this example, a Web client that provides a video recording function is taken as an example.

When the web client receives a video code stream, the web client can transmit the received video code stream to the local service through the Websocket connection.

When the local service receives the video stream transmitted by the Web client through the Websocket connection, the local service can transcode the received video stream and convert it into a specified format, such as Moving Picture Experts Group 4 (MP4) format and store the converted video stream to the designated local storage space to form a video file.

Here, after the local service successfully stores the processed video stream to the designated local storage space, the local service can return a data writing success notification message to the Web client, so that the Web client can confirm the successful completion of the data writing.

In this example, when the Web client determines that the video stream that needs to form a video file is written successfully, the Web client can send a data stop writing instruction to the local service through the Websocket connection to notify the local service that the data writing is completed. When the local service receives the instruction to stop writing the data, the local service no longer stores the data received through the Websocket connection in the designated local storage space.

In this example, after the Web client establishes a Websocket connection with the local service, before data transmission, the Web client can send a data processing instruction including a data storage policy to the local service, where the data storage policy is for temporary storage or long-term storage, so that the local service can perform temporary storage or long-term storage on the data transmitted through the Websocket connection.

Here, when the data storage policy included in the data processing instruction received by the local service is a data storage policy used to indicate that data is temporarily stored, the local service can return the data in the first designated local storage space to the Web client when the local service receives the instruction to stop writing data, and delete the data stored in the first designated local storage space.

When the data storage policy included in the data processing instruction received by the local service is a data storage policy used to indicate that data is stored for a long term, the local service can return to the storage path corresponding to the second designated local storage space to the Web client when receiving the instruction to stop writing data.

When the local service receives an access request for the storage path, the local service can respond to the access request to access the storage path.

In this example of the present disclosure, by establishing a data connection with the Web client, and receiving the data transmitted by the Web client through the data connection, and then storing the received data in the designated local storage space. When the browser does not support storing the data locally on the PC, it can enable storing the data of the Web client on the PC, which can prevent the data of the browser from occupying the memory of the PC and improve the reliability and stability of the system.
